Why do humans act with such unreasonable hostility with prolonged exposure to an Original One?
I have for many years been studying the psyche of humans. Their irascible behavior that they try to hide, but is always there, reveals itself with prolonged, in-person contact with a holy master, because of a change in their brainwave pattern and the flushing of toxins from the liver.
Humans aren't integrated — the Jekyll and Hyde syndrome — which makes them volatile and unpredictable. Furthermore, the vast majority have codependent relationships. This functions according to the codependent triangle I've often spoken of. In leg one of the triangle, they adore you, and in leg two they try to control you (because you "owe" them, because they've adored you), and then in leg three they revile you, if you don't let them control you.
In summary, a holy master flushes out their worst sides that they manage otherwise to keep hidden — most of the time.
